Baba Kama 8:3

If a person strikes one of his parents but he doesn’t make a wound, or if one person wounds another on Yom Kippur, he is liable for all forms of payment. If one wounds a Jewish servant, he is liable for all forms of payment except for lost wages for the period that the injured party is in his employ. One who injures a non-Jewish servant belonging to another person is responsible for all forms of payment, though Rabbi Yehuda says that one doesn’t pay for embarrassment if one injures a servant.

Baba Kama 8:4

A person who collides with one who has congenital deafness, one lacking mental competence or a minor is at a disadvantage because one is liable for injuring them but they are not liable for injuring others. Colliding with a male or female servant also places one at a disadvantage for the same reason, but if a female servant is divorced or a male servant is released, then they must pay for any injuries they may have inflicted earlier.
